According to Burns, the series was 10 years in the making, and includes “digitally re-mastered archival footage from sources around the globe … historic television broadcasts, evocative home movies, and secret audio recordings from inside the Kennedy, Johnson, and Nixon administrations.”

Burns told Rolling Stone that the idea of a film about the Vietnam War came as he and Novick were editing the series “The War” about World War II.

"I turned to Lynn while we sitting at the editing table and, completely out of the blue, said, 'We have to do Vietnam,'" Burns told Rolling Stone. Novick said, 'I asked, 'Of course, but what part?' He said, 'All of it.' It was like the last part of an unspoken conversation that had been going on a long time."
